<p>FYI, I am considering a stable point release. We have a number of stable-accepted patches, including a soundness fix. <a href="https://github.com/rust-lang/rust/pull/78151">https://github.com/rust-lang/rust/pull/78151</a></p>
<p><span class="user-mention" data-user-id="211727">@Jonas Schievink</span> do you perhaps have some insight into how common the soundness problem that PR exposes? Do we have a test case in "rust code", or is it theoretical?</p>

<p>I can only speculate, but I think switches on discriminant values often end up using SSA values in LLVM codegen, on which storage statements have no effects. That might limit the practical impact.</p>

<p>Hm. Okay. We're 4 weeks out from the next release, and realistically I'd probably not want to release until at least Thursday next week -- which puts us at 3 weeks out. I think that might not make it something we want to do, especially given the likely lack of impact.</p>

<p>note that I just disabled the infra pieces needed to put out a point release (azure pipelines gating on CI)</p>

<p>I'm not sure why that's broken, but since a point release is unlikely and we'll fully retire it when 1.48 comes out I'm not sure it's worth the time fixing it</p>

<p>if we decide to actually put out a point release I'll look into the issue again</p>

<p>Sounds good</p>

<p>I guess <a href="https://github.com/rust-lang/rust/issues/78283">https://github.com/rust-lang/rust/issues/78283</a> is now also relevant, though not having a fix yet, well, seems unclear that we'd have a point release for it</p>
